Apple says such widgets could be displayed or become available based on the content currently displayed in the Apple TV user interface. If the content is broadcasted, such as live television, then a widget could potentially be downloaded as part of the broadcast signal from a cable head-end, or provided through a separate communication such as an Internet connection, and then displayed over the content.
Elaborating further on its Apple TV iChat concept, Apple said widget interface could also include is a list of individuals currently online, as well as other controls, such as links to web sites and other resources that include information that may be of interest to the participants.
